Aldridge Announces an Updated 43-101 Resource Estimate
- Diamond drilling delivers increased tonnage and metal content -
TORONTO, Nov. 26, 2012 /CNW/ - Aldridge Minerals Inc. (TSX Venture: AGM) ("Aldridge" or the "Company") is pleased to announce an in-pit updated National Instrument 43-101 mineral resource estimate for its Yenipazar gold and polymetallic deposit in Turkey. The estimate is based on 54,248 metres of drilling, including 20,604 metres of diamond drilling.
Highlights of the November 2012 Resource Estimate
- Indicated resources total 29,669,000 tonnes, an increase of 11% since the June 2012 resource
- Contained metal content of gold and all other metals has increased since the June 2012 resource, highlighted by a 16% increase in contained copper and a 17% increase in contained zinc, all in the Indicated category.
"During 2012, we successfully completed a 10,000 metre diamond drilling program, which confirmed the continuity of the resource and resulted in a better understanding of the geology of the Yenipazar deposit and its mineralized zones," said Mario Caron, President and CEO of Aldridge. "With the increased tonnage and metal content, we have significantly enhanced the value of Yenipazar over the past 12 months. Our updated resource will form the basis for the reserves, mine plan, and cash flow analysis underpinning the feasibility study, which we look forward to delivering in Q1 2013."
Resource Summary
Compared to the June 2012 mineral resource estimate, the metal grades of the resource have remained fairly stable while the total size of the resource has increased. Due to the better quality of information provided by diamond drilling versus reverse circulation drilling, all reverse circulation holes drilled within a six-metre radius of a diamond drill hole have been excluded from the database.
The updated mineral resource is summarized in the following tables.
Total Mineral Resources (in-pit) @ NSR/t cut-off of US$15/t for Sulphides, US$12/t for Oxides, and US$15/t for Copper Enriched (1)(2)(3)(4)(5)

The total resources can be further broken down into the three major mineralized zones of the Yenipazar deposit, namely: sulphide, oxide and copper enriched zones.

| (1) | Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. |
| (2) | The quantity and grade of reported Inferred resources in this estimation are conceptual in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category. |
| (3) | The mineral resources in this estimate were calculated with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions. |
| (4) | The resources and Au equivalent ratios were calculated using the below recoveries (see October 16, 2012 press release for further details). Metal prices in US$ used were Au $1,435/oz, Ag $27/oz, Cu $3.50/lb, Pb $1.00/lb and Zn $0.95/lb. |
| Sulphides: Au 92%, Ag 90%, Cu 75%, Pb 75% and Zn 70%. | |
| Oxides: Au 75%, Ag 45%, Cu 0%, Pb 40% and Zn 0%. | |
| Copper Enriched: Au 82%, Ag 72%, Cu 50%, Pb 50% and Zn 30%. | |
| (5) | All resources are reported within an optimized pit shell. The $15/tonne Sulphide NSR cut-off value for resource reporting was derived from a processing cost of US$12.50/tonne and a G&A cost of US$2.50 per tonne. The $12/tonne Oxide NSR cut-off value for resource reporting was derived from a processing cost of US$9.50/tonne and a G&A cost of US$2.50 per tonne. Mining costs were US$1.35 and US$1.85 per tonne respectively for oxide and Cu enriched/sulphide and optimized pit slopes were 40 degrees. |
Metal Prices
It was determined that three-year trailing average metal prices be applied (see above footnotes). It is understood that more conservative metal prices may be used for the reserve estimate and cash flow analysis in the feasibility study, which is expected in Q1 2013.
Sensitivity Analysis
As evidenced by the tonnage/NSR tables and curves below, the resource is largely insensitive to NSR cut-off, and by extension, metal prices. This is especially true in the case of the sulphides, which compose approximately 80% of the resource.

About Aldridge
Aldridge is a near development stage mining company focused on advancing its Yenipazar gold and polymetallic VMS deposit (Ag, Cu, Pb, Zn) in Turkey - a country that is committed to developing its natural resources and is rapidly emerging as an economic powerhouse. Aldridge is currently building on its December 2010 Preliminary Economic Assessment with a feasibility study that we expect to complete in March 2013. The Yenipazar deposit is subject to an earn-in agreement with Alacer Gold Corp., wherein Aldridge can earn a 100% working interest subject to certain conditions, subject to a 6% net profit interest ("NPI", revenues less operational costs) until revenues of US$165 million are generated, and a 10% NPI from there on.
